So here's a weird one... going through gear that I bought, and, umm, forgot about..
(I'm figuring out what to sell, what to keep. I have the entire Neptune lens system. Not sure why..)
Z6 + Sigma 70-200 f2.8 Sport. I don't normally use my Sigma 70-200 on the Z6 but on the D500 instead. However, I consider shooting a time trial event is a bit slower pace race. The z6 should be able to handle it. For the most, yes. But as soon as the rider is under 15ft away, the Z6 can't lock on or losing focus. I say about 40% of the time. Still useful...
One of the few shots the Z6 manages to lock on focus even the rider is under 15ft away...
